My cat has allot of health problems and allergies too many questions to ask

I have cat named saber who is the runt of the litter i got him he's always been sick with skin condition like alergy, as well as health questions that i can't understand. He has been urinating all over the house for a few years now and keep cleaning it. We figured out that his litter irritates his skin causing him to break out in huge rashes that usually comes from flea bytes allergies, and we don't know what to do because he can't be an outside cat due to the 40f below zero during the winter. he also has some near the suface of the skin toumors that i've read to be non leathal. If anyone has any good advice or products that may be of some use i'm all ears.

Make sure you clean up the urine spray with an enzymatic cleaner such as nature's miracle. 

Go see your vet regarding the allergies and the inappropriate urination to make sure that it is not a UTI. 

 

Has he been to the vet at all? This really needs some professional help.

His urinating issues warrant a vet visit immediately. :nod:

These are the other steps I would take: change the litter to either corn, walnut, newspaper, or something else other than clay; add another litter box; and buy a black light and clean all pee spots with an enzymatic cleaner.

Let us know how the vet visit goes!

Is he neutered? If not, he is probably marking. Even so, a vet visit right away is very important, in case of urinary tract infection. And if he is not neutered, have it done.

If he has a flea allergy you need to put him on a safe effective flea product such as frontline plus, and de-flea your house.

It's quite possible the food he is eating may be causing him significant problems. What are you feeding him? Some cats are really sensitive to a lot of the things put into commercial cat foods.

Definitely keep him inside.
